  Bar screen is used to protect the plant against the entry of large objects likely to cause blockage in different parts of the installation and to separate and extract easily bulky matter carried in the raw influent likely to interfere with subsequent operation or to create complication.

  The effectiveness of coarse screening depends upon the spacing between the bars. We can distinguish between:

Fine screening, with spacing from 3 to 12 m
* Medium screening, with spacing from 12 to 25 mm
* Coarse screening, with spacing from 50 to 100 mm

 
Screening is performed either with manually-cleaned bar screen or ( necessarily, when the plant is sufficiently large) with an automatically-cleaned bar screen called a mechanical bar screen.

Mechanical bar screens are often protected by pre-screening, using a bar screen with a wider spacing (3-100 mm) which is customarily cleaned manually, but may also be automatic in case of very large installations or where the raw water carries appreciable quantities of coarse matter.
